What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2007 Mercedes-Benz G55, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
The vehicle entered dealer custody in 08/2025 after a dead battery / lockout repair event and was returned by the dealer on 01/08/2026 after months in dealer custody for repair work. Before entering dealer custody, the vehicle was drivable. The dealer documented a completed road test and inspection, but the vehicle was returned in unsafe and inoperable condition. Immediately after dealer return, on the drive home, the vehicle shook violently and emitted a strong burning smell, requiring multiple stops. The condition was later duplicated with dealer personnel during a road test. Despite that, the dealer refused meaningful diagnostic work and later returned the vehicle by flatbed. Since that return, the front brakes appear seized/engaged. If the vehicle is placed in drive, it remains stationary. If throttle is applied, it moves only slightly while squealing as though the brakes are locked on. The vehicle is not safely drivable and has remained inoperable since 01/08/2026. This created a safety risk because the vehicle was returned for use on public roads despite violent shaking, burning odor, and what appears to be brake seizure/drag. The symptoms were reproducible and were brought to the dealer’s attention immediately. The vehicle remains available for inspection.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
